documentation and potentially other activities based on its relative significance. EBR-I is exempt from
this process due to its status as a National Historic Landmark.
In the event a project is proposed that will substantially alter or demolish EBR-I, DOE-ID will follow
the provisions outlined in 36 CFR 800. For all other DOE-ID-owned buildings surveyed to date,
mitigative recordation will be conducted as follows:
Signature Properties. DOE-ID will follow 36 CFR 800.3 through 800.7. In addition, the DOE-HQ
chief historian will become a consulting party and a signatory to any agreements that may develop
and the AC HP will be invited to participate. Serious consideration will be given to preservation in
place.
Category 1 Properties. If an architectural property housed a reactor or a significant process (e.g.,
ETR at RTC or the Fuel Processing Building at INTEC), was constructed during the defined period of
significance (1942–1970), or is determined to have exceptional importance, that architectural property
will form the primary property in a HABS/HAER study. The primary facility and its historic features
will be thoroughly documented to HABS/HAER Level II standards. The complex of buildings,
structures, and objects directly supporting the primary facility or process will be incorporated into the
HABS/HAER study (HABS/HAER Collections 1983). A single HABS/HAER document might
include several structures across the categories (e.g., the TAN Hot Shop, Maintenance Shop, and
Administration Building). Category 1 buildings will not be adversely impacted prior to approval of
the appropriate HABS/HAER report by the Idaho SHPO and National Park Service.
Category 2 Properties. If an architectural property is an integral component in the reactor or process
complex (e.g., cooling tower, heat exchanger, or reactor coolant pump house), its interior, when
possible, and exterior will be photographed with large-format, archivally processed, black-and-white
film. Photographs will include one photograph of each side of the building or structure, oblique
photographs showing the relationship of the building or structure to associated buildings or structures
or landscape, and interior photographs that illustrate historic features. The photographs will be
preserved along with architectural and engineering drawings that depict elevations, sections, details,
and historic features; and with available historic photographs of construction, manufacture, and other
activities or experiments, when possible. When a HABS/HAER study is required for the key building
or structure in a complex, these photographs and other documents will become part of the study.
Category 3 Properties. If an architectural property such as a guardhouse, cafeteria, or warehouse
was contributing, but was not directly related to the key building or process, it will be documented
with 35-mm reconnaissance-level photographs and the completion of an Idaho Historic Sites
Inventory form. This documentation will be preserved by the INL CRM Office and made available to
scholars, researchers, and other interested parties. When appropriate, some 35-mm photographs will
be included in HABS/HAER reports to illustrate the narrative.
If an undertaking is proposed that involves properties that have not been surveyed or evaluated,
surveys and evaluations will be completed and, in the event that they will be adversely impacted, the
mitigation methodology previously described will be used, or new methodology will be developed in
consultation with the Idaho SHPO, Advisory Council, Tribes, and other stakeholders, as appropriate. The
new methodology will be incorporated into this plan or a memorandum of agreement will be developed.
Responsibilities and Consultations
The collection of data and preliminary determination of National Register eligibility are the
responsibility of the INL CRM Office on behalf of DOE-ID. Consultation is initiated with the Idaho
SHPO, Advisory Council (when appropriate), and other interested parties via a letter report that includes:
